Navigating around in a document can be challenging on your phone because it's hard to get around the page. You don't have to be frustrated by that anymore as your iPhone 6 hooks you up with an easier way to zip around the screen.
Simply hold your iPhone 6 or 6 Plus in a horizontal position while using the keyboard and you get forward and backward cursor buttons on the upper right side of the keyboard that provide you with the ability to move the cursor around and position it wherever you want it. This is not an option that exists in vertical mode, when Display Zoom is enabled, or on earlier iPhone models, but it is incredibly useful and makes life much easier.
